Just to bump this up - I ended up installing the Dexter EZ Flex suspension system. This system replaces the solid mounted triangle leaf perch with one that flexes and provides independent axle movement over bumps. https://www.etrailer.com/Trailer-Leaf-Spring-Suspension/Dexter-Axle/K71-652-00.html
I can say this product is worth every penny. While I had the wheels off I installed Goodyear tires. My camper is smooth as glass. Living in metro NY means I tow over the worst roads in the country so for me, itís cheap insurance. 100% satisfied and it really, really changed the ride quality and handling of my trailer.
Yes. Install was easy. Hardest part was jacking up the camper!
I ordered from E-trailer and they were great. You can call them and give your trailer specs and they tell you which kit to get. The biggest concern is your axle spacing... there are different kits for different spacing.
Again, I highly recommend the kit. You get replacement shackles with grease zerks, upgraded shackles and bolts, etc. it’s top notch. Only thing I noticed is it dropped my ride height by about an inch. I think the upgraded shackles are a little longer to allow more axle articulation so it adds a bit of drop. I think my trailer rides better now with the slightly lower height.
